What happened to the blue highlights on his face? They just disappeared as the painting progressed. For the hair, I think you should block it in with a very dark gray and build it up to the white. Maybe that way the roots will seem to have more depth.

This is almost a year old - I don't remember but I suppose I thought the blue was a bit too much.I'm not really sure what you're talking about regarding the hair. Using a dark grey for the shadows instead of the lighter value I used would result in salt 'n' pepper hair and that's not really the effect I was hoping for.

Hoho I just noticed through the process here that the blue-ish green background really brings out his eyes.Not to mention the color interaction on his back and front Interesting what you can pull out through the process!
